Transmission service urgent message came up. Low oil pressure warning also came on . Stopped car , shut off engine and checked engine oil level , and it was perfect in safe area. Restarted car oil warning went out and transmission seemed normal . Then suddenly transmission while in drive will not down shift either automatically or manually. Any ideas?
Transmission slips sometimes will not go into any gear. Can let it sit for awhile start it up and it will shift normal
will not up-shift from 2d to 3d normally, but if I can really slowly increase the speed sometimes it will shift and then be OK till I have to stop for something. Later I learned to pull over, shut off engine, restart and then do the slow sneak up. Dealer said "new xmsn for $4710 and new control computer for $700"
